Audi TT Roadster 3.2 Quattro: $44,500

This car boasts a 250-horsepower six-cylinder engine, and the latest generation of Audi’s Quattro all-wheel drive. In normal driving, 85% of the torque goes to the front wheels. But in heavy acceleration or extreme maneuvering, it can transfer up to 100%, front or rear. Competing all-wheel-drive systems, and even some other Audis, have a more limited range.
